MLS Heineken Rivalry Week concludes with another meeting of intense Cascadia Cup foes, as the Portland Timbers and Seattle Sounders FC face off yet again on Sunday evening at Providence Park before a FOX Sports 1 audience. Sounders FC won earlier this season in a league meeting, and just a week ago, the teams met in a bitterly contested U.S. Open Cup match, won by the Timbers. Both teams are coming off midweek defeats, the Timbers having their record four-game league winning run put to an end in a 5-0 crash at the LA Galaxy, while Sounders FC suffered a second consecutive MLS loss in a 1-0 defeat at Philadelphia Union.

The teams are meeting for the second time in league play this season, Clint Dempsey scoring the game’s lone goal for a Sounders FC victory April 26 in Seattle.

The teams also met in a fractious affair in the fourth round of the U.S. Open Cup last Tuesday, Sounders FC having three players sent off in a 3-1 Timbers win. Rodney Wallace and Maximiliano Urruti scored in extra time to send the Timbers through, just the second time in their MLS history that Sounders FC have been eliminated in their first match in the competition.

The Timbers have never won in Seattle in regular season play, Sounders FC now with a 4-0-2 league record in games at CenturyLink Field. But the Timbers did win there in the MLS Cup Playoffs in 2013, as well as the Open Cup matchup this year.

Versions of the club have faced one another in the NASL, Western Soccer League, APSL/A-League/USL First Division and now MLS. Overall, the clubs have met 90 times in official competitions, Seattle winning 46 times, Portland winning 32, and 12 draws.
